Upon landing in Thailand, Manchester City chairman Thaksin Shinawatra ruled out a return to politics.
The 58-year-old former Thai Prime Minister, who took over City last summer, was taken into custody by police after his arrival at Suvarnabhumi International Airport on a Thai Airways flight from Hong Kong.
Shinawatra then held a press conference at The Peninsula hotel in Bangkok where he stressed he was in Thailand solely to clear his name.
"I have returned to prove my innocence and restore my reputation, which has been unfairly tarnished," he said in the Bangkok Post.
"I will not return to the political stage.
"I am 59 this year, so I just want to enjoy the last stages of my life with my family, in my country. I will die on Thai soil.
"There is nowhere in the world where I and my family can stay as happily as in Thailand."
He had earlier told reporters before boarding the plane in Hong Kong: "I believe in the Thai justice system, especially the court system. Normally in justice systems everywhere, a person is innocent until proved guilty."
